So, as we all know, PS2 is a fairly CPU-heavy game. The obvious choice for improving your framerate would be to overclock your CPU, but mine refuses to overclock to a barely acceptable level. Setup is: i5-4670K Z97 Gaming 5(MS-7917) 12 GB Ballistix Tactical @1600MH'z MSI Geforce GTX 970 @1101MH'z Coolmaster 212 Hyper EVO From what I've come to understand, it should be perfectly reasonable for a 4670k to reach a least 4.2GH'z, and every hertz makes an impact on your performance. I've become extremely frustrated, as though I understand that much of CPU Overclock capacity is luck of the draw, I find it absurd that I can't even make it to what most motherboard's built-in overclocking profile would set it to. I've tried ramping up my voltage all the way to 1.4, but still no go. No matter what systems I fiddle with, I can't make it stable anything past 3.9GH'z... Technically. The system runs stable at 4.0GH'z at idle, but when benchmarking and even occasionally stressful gaming sessions can cause it to kick the bucket. Any expert overclockers advice?
